SHEAR ENFORCEMENT FOR SLABS

Tests have established that punching shear in slabs can be effectively resisted by reinforcement consisting of vertical rods mechanically anchored at top and bottom slabs. ACI 318 sets out the principles of design for slab shear reinforcement and makes specific reference to stirrups and shear heads. This report reviews other available types and makes recommendations for their design. The application of these recommendations is illustrated through a numerical example.
